Not dead, but not mainstream. It is morphing into a niche market for audiophiles only--just like vinyl. With universal machines proliferating, those who are willing to pay will get SACDs. Sadly, few people are willing to pay for sound quality, so we are going to see a lot more MP3's and even less SACDs. I like vinyl, but I really do prefer a well recorded SACD. Unfortunately the blinkin record companies, looking for the fast buck, don't often make an effort to make a decent SACD. A good example is Norah Jones 1st album, the SACD is awful. I just wish people would be willing to pay for fidelity. SAd thing is a lot of "audiophiles" won't pay extra.
